Abstract

The pneumatic tire is designed particularly to counteract unwedging of the tire. It is mountable on a rim having a protrusion (referred to as "hump") of ordinary shape. The bead has two bead rings, one of which is close to the bead tip while the other assures the blocking of the former in case of strong axial forces, which permits the bead tip to cooperate more effectively with the hump of the rim.
